ChatGPT — April 28, 2026

Changed

• Easier model selection in ChatGPT
• We’re making it easier to choose the right model before you send a message. Model selection now appears in the composer, so you can find and switch models from the same place where you write your prompt. We’re also moving thinking effort controls into the model picker. When you choose a Thinking or Pro model, you can select the level of thinking effort directly from the model picker. This update is available on web to ChatGPT users on Plus, Pro, and Business plans.
